r 'Serial 'No. 405,528.

' y invention relates to Vaporizers, such as described in my original application, Serial,

No. 42 676, filed July 10, 1925, allowed May 3, 1926, forfeited Dec. 3, 1926, renewed March 10,1927, re-allowed February 18, 1929, and again forfeited. This. is a substitute for my former application filed July 1925, Serial No. 42,676. v My invention relates, generally, to an improved construction of vaporizer; and, the invention has for its principal object to provide a novel construction of forcefeed vaporizer general use in vaporizing liquids of all kinds, and forcibly discharging or delivering the same to the place of use.

With the objects of the invention in view, the same consists, primarily, in the novel vaporizer apparatus hereinafter set forth;

' and, the invention consists, furthermore, in

the novel arrangements and combinations of the various devices and parts, as wellas 111 the detailsof the construction of the same, as

more fully described in the following specification, and set forth in the claims appended thereto. v 1

The invention is shown by way of illustration in the accompanying drawings, in which l I Fig. 1 is a verticallongitudinal section of the novel vaporizer apparatus, made according to and embodying the principles of this invention; Fig. 2 is a transverse vertical secticn, taken on line 2.2 in Fig. 1; and Fig. 3 is another detail transverse vertical section, taken on line 33 in said Fig. 1, drawn to a larger scale.

Similar characters of reference are employed .in all the views, to indicate correspending parts.

The novel vaporizer device comprises a casing 5 which may be formed by a suitable casting, and which is shaped to provide an .interior intake cha mber,6. Leading into the lower end of said'intakc chamber 6 is an airintake passage 7, which is preferably pro vided, at its outer end, with a butter-fly or throttle valve 8. The inner end of said air intake passage 7 is upturned to extend vertically upward into said intake chamber 6, and is preferably internally shaped at its dis- Venturi tube portion 9. Also connected with said casing 5, in alignment with the upturned discharge end of said air-intake passage 7 below the same is a liquid intake chamber 10.

Extending upwardly from said liquid intake charge end so as to provide a restricted or adapted to control the de-- 7 is a liquid disfloat chamber 'device with saidliquid intake chamber 10. If desired, a suitable filter screen device 14 maybe arranged within said liquid intake chamber 10, intermediate the delivery conduit or pipe 13 and the liquid discharge nozzle 11. It will be understood that any desired construction and arrangement of means for delivering a liquid through the delivery conduit or pipe 13 to said liquid intake chamber 10 to supply the discharge nozzle 11 may be employed, and 1 do not, therefore, limit myself to the use of the float chamber device 12, which is merely illustrative of one form of liquid delivery supply and control.

The casing 5 is closed on its forward side by a cover-plate 15, having a centrally disposed outwardly projecting neck 16 provid-' ing a. discharge passage 17. Said neck 16 is externally threaded so that a casing 18 may be coupled therewith. Said casing 18 constitutes a vaporizing chamber 19, with which said discharge passage 17 communicates.

Said casing 18 is so shaped or formed as to provide, in connection with its inner or rearward face, an annular space adapted to form a heating chamber 20, which may be closed by the opposed face of the cover-plate 15, a suitable gasket 21 being provided to form a tight joint. A suitable heating medium serves in connection with said heating cham- .ber 20, for example an electrical heating element 22 mounted therein, which is adapted to generate heat to be transferred through the walls of said casing .18 to said vaporizing projecting internally threaded neck 26, into which may be threaded a discharge pipe or conduit 27 for conveying the generated vapor to the place of use or consum tion.

Mounted within said inta e chamber 6, for rotation therein in a transverse vertical plane, is a combined blower and nebulizer 28, the same intake passage 7 and the discharge passage 17, so that it exerts a suctiorreifect relative to the former and a propulsion eifect relative to the latter.

Mounted within the vaporizing chamber 19, for rotation therein in a transverse vertical plane, is a rotary plate 29, the same being located intermediate the passage 17 and the vapor discharge conduit 27. Y

Said blower and nebulizer 28 and said rotary plate 29 may be driven in any manner and from any source of power. found desirable. To such end, a shaft or spindle 30 is provided, upon which the said devices are fixed, said shaft or spindle 30 being driven by suitable power transmission' means.

When the vaporizer apparatus is put in operation, it functions as follows:

The combined blower and nebulizer 28 is rapidly rotated within the intake chamber 6, with the result that a'stream of air is sucked through the air-intake passage 7. The entering air stream is accelerated'in movement as it passes through the restriction'or Venturi tube portion 9, so that the liquid which is supplied to the discharge nozzle 11 is drawn or sprayed into the air stream, and roughly mixed therewith as it enters said intake chamber 6. The mixture of air and liquid thus drawn into the intake chamber 6 is thoroughly agitated by the rotating blower and nebulizer 28, so that the liquid is mechanically broken up into exceedingly minute particles, which are intimately mixed with and suspended in the air, forming a fine mist; in other words,

. the initially entering mixture of air and liquid is nebulized, i. e., turned into a mist or fog. Any heavy particles of liquid, not sufiiciently broken up or nebulized by the agitating action of the blower and nebulizer 28, are thrown by centrifugal force to the outer circumferential walls of the intake chamber 6, down which they descend by gravity into a depending well or trap 31'at the-lower portion of the casing 5. This well or trap is more or less heated by the heat conducted and transferred through its walls from the heating medium in the heating chamber 20, so

being located intermediate the air.

the apparatus would be water,

that the liquid collecting therein during o eration of the apparatus is va orized by-t e heat and returned into the mist discharged from the intake chamber 6 into the vaporizing chamber 19. a

The mist or nebulized mixture of air and liquid formed in the intake chamber 6 as above described, is ropelled from the outer side or face of the lflower and nebulizer 28 so as to be forced outwardly from said intake chamber 6, throughthepassage 17 into the vaporizing chamber 19. As the mist-like mixture of air and liquid enters the heated vaporizing chamber 19 it impinges against the surface of the rotating late 29, which is kept hot by the heat radiated into the vaporizing'chamber from the heating The minutely divided particles of liquid upon striking the plate 29 are vaporized (or gasified, as the case may be) and the resultant vapor is forced onward, by the propulsion efunder any other circumstances, will-descend chamber 20.

late 29 and thence out.-- ischarge pipe or'conduit into the trap or well 24 and will'be retained n therein subject to the action of the heat within the vaporizing chamber, and "conducted through the walls thereof, whereby the condensate will be eventually vaporized and dis: charged. 1 From the above description it will quite apparent, that-my novel vaporizing appara-. tus is capable of service in several fields. For example, it may be employed as a steam generator, in which case the liquid delivered to which when mixed with air and nebulized, and thereu on subjected to heat in the vaporizing cham er,

would be turned into steam which would be forcibly delivered through the discharge conduit or pipe 27 to the desired place of use.

The apparatus in such case would serve as a continuously operating steam generator of the flash type. The above described use of my novel apparatus is well illustrated in my United States Letters Patent, No. 1,649,337, dated November 15,1927. I

Another field of serviceto which my above described vaporizing apparatus is applicable is that of carburetionof combusti 'le liquid fuels, such as hydrocarbons.

Iam aware that various changes may made inthe general arrangements and combinations of the parts of my novel vaporizer,

apparatus, as well as in the details of construction ofthe same, without a departure from the scope of this invention as above described and as defined in the appended claims,

and therefore, I do notlimit this invention to the exact arrangements'and combinations and the construction of the devices and parts as shown and described.
